Well it can work because it diverts them from the digging to grooming themselves with the water. It’s worth trying it. Just squirt them anywhere because it’s water and it won’t hurt them.

But if it starts making her angry then it’s not a technique that will work.

I agree with Sarita, if the squirt bottle makes your bun angry or scared, I wouldn’t use it.

I usually start with just clapping and saying no. If that doesn’t work, I get closer, get louder, and will nudge Otto away from whatever he’s chewing. He’s actually very good and I rarely have to go the squirt bottle, but this is the point I use it. Honestly, he doesn’t seem to mind it that much, but I use it infrequently enough that it still gets a “what the heck?!” reaction and he stops what he’s doing.

I also find it helpful to cover up whatever he’s digging or chewing at. When he was digging in the corner of the room, I just put a grass mat down and let him dig at that for a while. And I find having tons of cardboard (a maze haven, boxes, etc) around helps because he much prefers to chew and dig on those than on my baseboards.

Some squirt bottles have a nozzle that you can twist for more of a misty spray than a stream of water. It’s more gentle and wider, so it’s startling but not as intense.

If he’s humping you, you can wear long pants so your ankles don’t show (cover your feet if you can stand it).

Also, try a little bit of white vinegar. Maybe dampen a cloth or paper towel and rub it on. Not a lot, but the smell is repellent to bunnies.
